UNITED STATES HOMER C. CHALK, OF SAN ANTGNIG, TEXAS.

ATTACHMENT FOR PBESSES.

Application filed October 28, 1921.

To (all whom it may concern:

Be it known that I, HOMER C. CHALK, a citizen of the United States, residing at San Antonio, in the county of BeXar and State of Texas, have invented new and uset'ul Improvements in Attachments for Presses, of which the following is a speciication.

My present invention has reference to a hay press attachment, and is designed to facilitate the wiring of the hay compressed in such presses.

An object is to produce an attachment of this character which can be applied to any ordinary construction of hay baling presses, and wherein the wires will be positively fed so that the bale can be wired by a single operator.

A further object is to produce a wiring attachment for hay presses which shall be of a comparatively simple construction, cheap to manufacture and market, readily arranged upon the press and which will be positive and accurate in operation.

The foregoing, and other objects which will appear as the nature oi the invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed by the drawings which accompany and which form part of this specification.

In the drawings Figure 1 is a perspective view of a portion of a press having the improvement applied thereto.

Figure 2 is a similar view upon a greatly enlarged scale and showing the arrange ment of parts when the division blocks have been moved into the baling chamber.

Figure 3 is a horizontal sectional view taken directly above the upper telescopic tubes, as disclosed in Figure 2.

Figure 4 is a fragmentary sectional view illustrating the manner in which the spring iul'luenced pin is held in its pocket when a division block is in the press before the removal thereof into the baling chamber.

Figure 5 is a fragmentary transverse sectional view on the line 5-5 of Figure 2.

Figure 6 is a sectional view on the line 6-( of Figure 3.

Figure 7 is a detail view of one of the guides.

Figure 8 is a detail sectional view through one of the division blocks.

Referring now to the drawings in detail,

Serial No. 511,043.

of the division blocks 5 is retained in the baling chamber when the other division blocks are in the press. Both boards 5, in the present instance, have their opposite faces, adjacent their top and bottom edges provided with oppositely arranged transverse grooves 6, and in each of these grooves there is a wire guide 7. Each guide is constructed of metal to include a flat base which is screwed or otherwise secured in the inner wall of the grooves 6, from the base there being extended arched sides 8 that terminate a slight distance away from each other, providing the guides with a central wire opening therethrough. l/Vith this construction it is not possible that the grooves be filled by obstructing material, as is common with the ordinary arrangement of such grooves and also with this construction the material cannot interfere with the wire.

Each division block 5, between the oppositely arranged wire guides has one of its edges provided with a pocket 9 and within this pocket there is pivoted, as at 10 the inner arm of an angle member 11. For the purpose of this description, the outer arm of the member 11 will be referred to as the finger thereof, the said finger being provided with a ball head 12, and the member 11 being influenced by a spring 13 to project the finger and the ball head through the pocket 9. The angle member 11 is swung upon its pivot 10 when the same is received in the baling press, but when the division block is moved to bring the same into the baling chamber, the spring will influence the member 11 to project its finger 10 through the open sides of the said baling chamber.

In addition to the division block construction, my improvement contemplates the employment of means for guiding the wire from one side of the press around the bale, the said means including a frame Ll which is lll) provided t-with U-shaped ends theaipper and lower parallel elements of the frame being disposed over the respective upper andlower boards of the balingchamber 3, the upper members or arms having threaded openings that receive therethrough binding screws; that contact with the upper board of the baling chamber. The parallel. or angle arms of the members let are connected by longitudinal-strips 16 respectively, andithe outer Or -vertical portions of-the members 14- are provided-with el-ongated slots 17. Through these slots 17 pass bolts 18 tliat are seeu'red "The -roundedend of the tube 29 is indicated on' -the-outer portions of substantiallyU- shaped members 19. 'The arms 2O ofthe U-shaped members 19 are arranged parallel with-thenrms of the u shaped members 14:, and the=bolts 1'8 are en'gaged by nuts 21, whereby the auxiliary frame, whoseends are provided by the U-shaped members 19 may be -adj-usted -vertieally on the main frame. The arms QO-ofthe auxiliaryframeliave arranged thereon plates 22 respectively. These plates are-pivoted, as at 28 to the arms 20 ofthe 1 outer l U-shaped inember 19, the arms 20 -of the inner U-sliaped member being.

It is also thought necessary to state that the showing and description have reference to a satisfactory embodiment of the invention as it now appears to me and that I am entitled to makeall such changes therefrom as fall within thescope of what is claimed.
